Specification of Letters Patent.

Patented Aeg. 17, 1909.

Application filed July 22, 1907. SerialNo. 354,961.

To all whom itl'mng/ concern.'

.Be it known that we, BnxJAiiiN .thermen f i and Anios OnLLnsoN,citizens ol the linited e States', residing in Brooklyn, eountyoiliings,

State of New York, have invented a certain new aiidrusefull Machine for(ilenchingI rlogether Sheet-Metal Cans and lheir Heads: and we do herebydeclare thi` lollow ing to be a iull, clear, and exact description oi'the invention,- such as will enable others skilled iii the' art to whichit appertains to make and use' the saine, reference being had to theaccomp anying drawings, and to characters of reference marked thereon,which form a part of this specification.

Our invention relates to can heading machinery, and it consists incertain improvements ,in such machinery having .,or their object toprovide means lor automatically machine of, say, the type illustrated inthe application for U. S. Letters Patent iiled February 28, `1905,#247,766 andA which it is unnecessary to describe herein moreparticularly than byA stating that it comprises Vlfour heading unitsbetween each two of 7 clined planes lor chutes down which the canswhich, at two points in the machine, the cans are fed .to be alternatelydistributed to said units -for heading. In the application referred .toit was roposed that the cans be introduced into t e machine by means ofin- `moved by their own Weight; this construction required, however, anincline oi' such n. pitch that cans 'filled or partially filled withliquid would lose considerable of their contents before they reached theheading means. By the present invention it is proposed to not only leedthe cans along a substantially horizontal plane but to also provide.l'or preliininarily rand temporarily clenching the heads thereon so asto prevent loss Oi' their contents during`- the feeding operation, itbeing remarked that the type of can which is particularly in mind isthat y,in which the cover o crates as a sort oi' a wedge onthe can boi ywhen thetwo are assembled and thus forms with the latter an adequateseal for the time being. l

The invention will be l'ound fully illustrated in the accompanyingdrawings, wherein, i i

d is a pedestal arranged back of the inal chine a and formed on one sidewith a dat face e against which is bolted a )latef partly supported bythe pedestal and by a le g. 'llic plate f affords bearings for a sliaipt7i' carrying a sprocket wheel 'i and a ear wheel j; said platestands atright ang es to the machine a and.I at its farther end it carries 1another shaft c on which is journaled a drum l. Over the' drum andsprocket wheel extends a ychain 'conveyer `m each of whose links isablock n having oneY end bifurcated and receiving the unbifurcated end ofthe next link, the two bein joined together by a ,pin o; the topof the book a is not flat,but 1s convex, as at p, Fig. 4 `the reason for thisgrows'out of the fact that since the can has a depending lower flangeits lower wall wouldbeiotherwise unsupported during the head appl ingoperation so that the pressure ofthe can cad. applying device wouldcause the bottoni to bulge and thus produce an unmarketable can. Theunbifurcated end-of each link is formed as an.. upwardly projectingfinger g. The cans are placed on this conveyer with the head looselyresting on each,

eachbetween two lingers 1 and disposed lengthwise on the conveyer.

Above ai@ pisa f there is balada ai@ flat face e of the pedestal danother plat/e 1^ formed with a bearing s. In this bearing is journaleda shaft t carrying at one end a cani. u and at the other end a sprocketwheel ci..

In the plate rist'ulciuined, onstuds a pair of levers z acting asparallel levers by virtue of being pivotal connected by a link l..

' 2 isa plunger lock having-a rear flat face 1 bearing square .againstthe levers. z, the same being carried by an adjustable pitinan 3suspended from a crank pin 4 on the cam a.

In the back ofthe plunger block 2 is a dovetailed groove 5 in whichworks, vertically, a

i' slide 6 Which is pivotally connected, by studs 7, to the free arms ofthe levers 2.

8 is a roller journaled on the stud on thel upper lever zinposition-tobe engaged by the periphery ofthe cam u. T e mechanismabove 4partially described and best shown in Figs. 4 and 5'operatessubstantially as follows: In the rotation of ,shaft t cam uis broughtagainst roller 8 while lherotation of the crank-pin is causing theplunger-block 2 to ascend; since the cani and upper llever z havedifferent centers of rnoven y nient, the action of the carn on theparallel levers 2 is `to cause them to swing on their the cam continuesto turn.

and until art 19`eomes within the path of a' "linger q, Wien cam urecedes from roller 8 as During the lat ter ,art of this operation7 theplunger block, whi ev s tilll descending, being allowed to I moreby'gravity to the right, thus following 'thernoveine'nt vot-the can,which is being cor-l respondingly nioved iin'ger g, luid the iplungerblock` continues this movement untill the stud 4 Qreaclniesfits' lowestliinit of inoveinent,`wher eupo`n 'it'bcgns to rise. In its rise, afteritclea'rsiingei" q, it of coursehas a vertical movement; aswell as,again, to the left. It will thus'lbe's'een that the plunger blockaccommodates "itselff to the? advance lof the conv eyer m as itdescends, moving-to theright and thus with-the conveyer whilethe'headiapplying operation is proceeding.

Thusvit is `unnecessary tostop the conveyer 'bending devices to theirncrinal or openposievery time a head is applied, so that the operationis not only quickened but the jarring of the cans, from alternatelystarting and stopping, prevented.

The plate f is formed with a shell' 1'0 on which the up er stretch of'the conveycrm. rests. The pliite itself forms the back wall of saidshcliagainst which the cans rest when they are placed on the conveyor; whenthey are ready for thc head applyingr operation, i. e., about 'oppositethe pedestal d,-

they pass in behind a lront wall l1 secured lo thc shelll 10. Said frontwall and the opposed portion'of the plate f have opposed groovcd guidesl2 which receive the llanges of the head and body, (see Figs. 3 and 5)when the can and head are assin(T the ied-v estal.

The plunger comprises, together with thev block 2 above dcscri ied, ameans for pressing the can heads against the cans and for clenching thehead and can edges, 0., bending thesarne over together in relativelylimited portions so that the can and head are suflciently interlockedlfor the time boing` so that the head will not bcconi'e dislodgedduringT the subsequent treatment. Said moans is illustrated in detail inFigs. 14 to 24. 13

is a block attached to the under side of the plunger block 2 by bolts1'4. At opposite points it is provided with vertical grooves 15 1n whichar`e`secu1ed, by screws 1G, wedge pieces 17. 18 designates four verticalholes in said block. block 13 and 'movable' vertical y relativelyinglscrcws 20 which penetrate the holes 18 in block 13 (having then'heads 1n countersinks 19 yis avblock dis osed below thereto, the samecarrying upwardly extend- 21 of the latter) whereby they guide the block19 in its movements; springs 22 intorposed between thel two blocks 'andcoiled about the screws press the block`19 downwardly to the linitalfordcd by the heads ol the screws. The block 19 is formed on its undersid'e with a groo'vc23 and a groove 124 Countersunk therein; in'tlicgroove 23 is arranged a pair of slides 2.5 pressed apart by a spiralspring in. the groove 24. A :plate 27, secured to the under side of theblock 1l) by screws 28 arranged in the holesQQ, keeps the spring 26 inplace even though a rplate 30, which is secured by screws 31 to theblock,

tions. In order to prevent the screws 2() roin turning,l their lowerends are recessed, as at 34, to receive keys 35 set in grooves 36 in theiio under side of the blockand held in place by the plate 80. When thelunger block descends and the block 19A ears against the head of the canthe pressure efl'ects a rela tively upward movementof said block in the,

shown a groove 37-in Figs. 15, 22 and 24.

The end of the plate f adjacent the machine a is formed as a bearing 38in which is journaled a shaft 39 carrying yat one onda spur Wl'1eelf40meshing with thev sprocket wheel j and at the other end a peripherally.grooved cam 41. Above vthis bearing.: the fplateis extended and formedwith a small table 42 on which is secured a bracket 4S. 0 l(ln thisbracket and two brackets 44 (sei Figs. 2 and 10), which latter aresecured to the platform c of the machine ai, rest the ends of beltsupports 45, the same-,being countersunk in the tops ofthe brackets. Inthe bracket 43 are journaled two rollers 46 set with their axes at rightangles to the belt supports 45, Whichoccupy a' position in the form ofthe letter V as `seenin Fig. 2; correspondingly, in each bracket 41' isjournaled a roller 47. Over each roller 46 and the correisponding roller47 extends an endless belt 48, the upper stretch of which rests on thebelt lsupport 45.

49 is a vertical shaft journaled in the (i5 bracket 43 between the beltsupports and limited against ,vertical movement therein by a switch ,5Gon its up er end and a crank 51 on its lower end, a ro ler 52 on thecrank "being engaged in the groove of cam 41. As hereinafter explained,the cam 41 Oscillates shaft 49 throughthe crank 51 and thus.l

vibrates the switchin such manner that the cans are fed on to the belts48 alternately as' they come from the clenchingoperation. When the cans'finally reach the niachme c they are intended to' do so side oh, a caninarked A being so" shown in Fig. 2; when the cans leave the clenchingoperation they move endwise, and in order to effect their change ofposition so to stand side on on the belts 48, the switch 50 lhas itsfreel end formed as a blade 53 havin converging side edges 54. A moreparticu ar descrlption of the manner i'n which the cans change theirposition will follow later on.

Inrorder to guide the cans they are conveyed by the belts 48 to themachine (L, .tlat sidezstrips 55 are provided, the same being supportedby spacers 56 orrth'e belt sup- 60 ports 45 and blocks 57 secured to thesides -oi' said belt supports. These strips stand high enough` from thebelts 48, which they overlap,` so that the lower can edfres just "aboutitbetween the belt and sai-d The edge Lo engagmg portionof each bendmgferire '1s y p strips,v 6.5 vallowing for slight variations in thethickness of the edges ol the caps. Jamming of the cans is efectuallyprevented as'they are about to more on to the Aplatform c ol' themachine a by a guide 5S which extends longitudinally over each belt 48and close enough'to the same so to keep euch can squarely against itsbelt, said guido being carried by arches 50. f

6() arc entrance guides gi'ooved on their insirlea, as at 61, toaccommodate the lower flanges ol' the cans, and arranged on tbe bracket43.

ln order to keep the belts 4S taut, a

,weighted roller 62 journaled in'a lever 63 lult-.ruined in each`bracket '44 is arranged to rest on the lower stretch of the belt. Eachbelt is driven from a pulley 64 on the shalt Z) I of the machine e by abelt 65 extending. around guide rollers 66 andY then around a pulley 67on the shaft of the roller 47.

68 is a chain passing around the sprocket wheels j and u and alsoaro'und a sprocket wheel 69 on shaft b, the same acting, throughmechanism already described, to drive the conveyer m, re yiprocate theplunger, and vibrate the switcih 50.

When the cans and heads have been operated upon by the clenching meansthe conveyor 'm advances them successively on to thebracket 43. Theswitch 45 vibrates as fast as each can approaches, first to one side andthen to the other. The center of movement o'l the switch, c'. e., shaft49, is alined with the centers of the approachingr cans so that,laccording as the extremity of the switch is at one limit or the other,so the blade 53 is opposite the one or the other ol" the further cornersof the nearest approacln ing can. As this can is advanced by theconveyer m causing the cans behind it to feed it forward, one of thefarther corners thereof is engaged by the blade 53, which now moves and,since it has contact theiewith in its rear part, displaces' the canlaterally in such manncr'thatit sinmltammu::ly turns ,it until theadjoiningl edge 5?, olA the blade rests squarely against the side ol'the can, whereupon the switch directsl it i nto, its properposition,side on, on the belt 48. Once on the belt, it is carried forward therwby to the machine a, the same operation then occurring witl'r respect tothe can behindit.'
